But two men were left in the camp; the name of one [was] Eldad, and the name of the second [was] Medad, and the spirit rested on them; they were among those who were written [down], but they did not go out to the tent, so they prophesied in the camp. So a boy ran and told Moses and said, "Eldad and Medad [are] prophesying in the camp."
